Access to artemisinin-based combination therapy (ACT) and quinine in malaria holoendemic regions of western Kenya

Findings from this research show a low availability of subsidized Artemisinin-based combination therapy (ACT) in the form of artemether-lumefantrine (AL). There is higher frequency of stock-outs in government facilities, while the private sector sells AL at higher prices, thus making it less affordable. In addition, frequent stock-outs of the required antimalarials for different weight groups calls for more emphasis on the implementation of malaria treatment policy. Evaluation of the subsidy policy, its implementation and role in malaria burden is necessary. ACT has been adopted following widespread malarial parasite resistance to more affordable antimalarial drugs

Factors determining anti-malarial drug use in a peri-urban population from malaria holoendemic region of western kenya

<p>Abstract</p> <p>Background</p> <p>Interventions to reverse trends in malaria-related morbidity and mortality in Kenya focus on preventive strategies and drug efficacy. However, the pattern of use of anti-malarials in malaria-endemic populations, such as in western Kenya, is still poorly understood. It is critical to understand the patterns of anti-malarial drug use to ascertain that the currently applied new combination therapy to malaria treatment, will achieve sustained cure rates and protection against parasite resistance. Therefore, this cross-sectional study was designed to determine the patterns of use of anti-malarial drugs in households (n = 397) in peri-urban location of Manyatta-B sub-location in Kisumu in western Kenya.</p> <p>Methods</p> <p>Household factors, associated with the pattern of anti-malarials use, were evaluated. Using clusters, questionnaire was administered to a particular household member who had the most recent malaria episode (within <2 weeks) and used an anti-malarial for cure. Mothers/caretakers provided information for children aged <13 years.</p> <p>Results</p> <p>Stratification of the type of anti-malarial drugs taken revealed that 37.0% used sulphadoxine/pyrimethamine (SP), 32.0% artemisinin-based combined therapy (ACT), 11.1% anti-pyretics, 7.3% chloroquine (CQ), 7.1% quinine, 2.5% amodiaquine (AQ), while 3.0% used others which were perceived as anti-malarials (cough syrups and antibiotics). In a regression model, it was demonstrated that age (<it>P </it>= 0.050), household size (<it>P </it>= 0.047), household head (<it>P </it>= 0.049), household source of income (<it>P </it>= 0.015), monthly income (<it>P </it>= 0.020), duration of use (<it>P </it>= 0.029), dosage of drugs taken (<it>P </it>= 0.036), and source of drugs (<it>P </it>= 0.005) significantly influenced anti-malarial drug use. Overall, 38.8% of respondents used drugs as recommended by the Ministry of Health.</p> <p>Conclusion</p> <p>This study demonstrates that consumers require access to correct and comprehensible information associated with use of drugs, including self-prescription. There is potential need by the Kenyan government to improve malaria care and decrease malaria-related morbidity and mortality by increasing drug affordability, ensuring that the recommended anti-malarial drugs are easily available in all government approved drug outlets and educates the local shopkeepers on the symptoms and appropriate treatment of malaria. Following a switch to ACT in national drug policy, education on awareness and behaviour change is recommended, since the efficacy of ACT alone is not sufficient to reduce morbidity and mortality due to malaria.</p

Provider knowledge of treatment policy and dosing regimen with artemether-lumefantrine and quinine in malaria-endemic areas of western Kenya

BACKGROUND: Due to widespread anti-malarial drug resistance in many countries, Kenya included, artemisinin-based Combination Therapy (ACT) has been adopted as the most effective treatment option against malaria. Artemether-lumefantrine (AL) is the first-line ACT for treatment of uncomplicated malaria in Kenya, while quinine is preferred for complicated and severe malaria. Information on the providers’ knowledge and practices prior to or during AL and quinine implementation is scanty. The current study evaluated providers’ knowledge and practices of treatment policy and dosing regimens with AL and quinine in the public, private and not-for-profit drug outlets. METHODS: A cross-sectional survey using three-stage sampling of 288 (126 public, 96 private and 66 not-for-profits) providers in drug outlets was conducted in western Kenya in two Plasmodium falciparum-endemic regions with varying malarial risk. Information on provider in-service training, knowledge (qualification, treatment policy, dosing regimen, recently banned anti-malarials) and on practices (request for written prescription, prescription of AL, selling partial packs and advice given to patients after prescription), was collected. RESULTS: Only 15.6% of providers in private outlets had received any in-service training on AL use. All (100%) in public and majority (98.4%) in not-for-profit outlets mentioned AL as first line-treatment drug. Quinine was mentioned as second-line drug by 47.9% in private outlets. A total of 92.0% in public, 57.3% in private and 78.8% in not-for-profit outlets stated correct AL dose for adults. A total of 85.7% of providers in public, 30.2% in private and 41.0% in not-for-profit outlets were aware that SP recommendations changed from treatment for mild malaria to IPTp in high risk areas. In-service training influenced treatment regimen for uncomplicated malaria (P = 0.039 and P = 0.039) and severe malaria (P < 0.0001 and P = 0.002) in children and adults, respectively. Most (82.3%) of private outlets sell partial packs of AL while 72.4% do not request for written prescription for AL. In-service training influenced request for written prescription (P = 0.001), AL prescription (P < 0.0001) and selling of partial packs (P < 0.0001). CONCLUSION: Public-sector providers have higher knowledge on treatment policy and dosing regimen on recommended anti-malarials. Changes in treatment guidelines should be accompanied by subsequent implementation activities involving all sector players in unbiased strategies

Knowledge and behaviour as determinants of anti-malarial drug use in a peri-urban population from malaria holoendemic region of western Kenya

Abstract Background The appropriate use of anti-malarial drugs determines therapeutic efficacy and the emergence and spread of drug-resistant malaria. Strategies for improving drug compliance require accurate information about current practices at the consumer level. This is to ascertain that the currently applied new combination therapy to malaria treatment will achieve sustained cure rates and protection against parasite resistance. Therefore, this cross-sectional study was designed to determine knowledge and behaviour of the consumers in households (n = 397) in peri-urban location in a malaria holoendemic region of western Kenya. Methods The knowledge and behaviour associated with anti-malarial use were evaluated. Using clusters, a questionnaire was administered to a particular household member who had the most recent malaria episode (within Results Consumers' knowledge on dosage and duration/frequency demonstrated that only 29.4% used the correct artemisinin-based combination therapy (ACT) dosage. Most respondents who used quinine identified the correct duration of use (96.4%) since its administration was entirely at health facilities. To assess behaviours during use of anti-malarial drugs, respondents were stratified into those who took drugs with prescription (39.4%) and without prescription (61.6%). For those without prescription, the reasons given were; procedure of acquisition less costly (39.0%), took same drug for similar symptoms (23.0%), not satisfied with health services (15.5%), neighbour/friend/relative previously taken the same drug (12.5%) and health institution was far from their location (10%). Conclusion Majority of consumers in the study area were knowledgeable on the symptoms of malaria. In addition, majority acquired ineffective anti-malarial drugs for treatment and reported sub-optimal treatment regimens with the currently recommended drugs. Furthermore, behaviours which constrain the successful up-scaling of ACT were common, creating a challenge in the desire to turn efficacy to effectiveness of the combination therapy programme. It will be important to direct and focus interventions in creating awareness on the importance of using recommended drugs to lessen the use of less efficacious anti-malarials. In addition, the consumers need to be educated on the importance of drug adherence in such areas to reduce the emergence and spread of drug-resistant malaria.</p
